Ground access to San Luis (All Airports) (SLUA) includes taxis, app-based rideshares, airport shuttles and local buses.

Arriving at Castries (Any) FAQs
The 'Cheapest Economy Fare (ECONOMY)' typically refers to the lowest-priced economy-class ticket available, often offered by low-cost carriers or as basic economy on legacy airlines. These fares usually include a seat and limited carry-on allowance; checked baggage, seat selection, and changes often cost extra.
Budget and economy fares often route through major hubs such as Buenos Aires, Miami, Panama City, Bogotá or São Paulo depending on origin and carrier networks. These cities are frequent connection points where low-cost and legacy carriers operate competitive economy routes.
In January, many cheap economy fares arrive during off-peak hours or on midweek days to keep costs low; however, January is still a busy month for summer travel so arrival slots can be competitive. Expect potential extra charges for late arrival luggage handling or peak-day surcharges.
The cheapest economy fares are usually non-refundable and have limited or no free changes; carriers charge change fees and fare differences for modifications. If flexibility matters, compare basic economy vs standard economy and consider purchasing a flexible fare or add-on protection at booking.
Budget travelers arriving on an economy fare should prepare their passport, visas (if required), and any health documentation before landing. Low-cost tickets don't change arrival procedures, but they often require strict adherence to carry-on limits and may have separate, lower-cost baggage drop counters.
July often sees elevated demand for family and winter travel, which can reduce the availability of the cheapest economy seats; booking earlier and traveling midweek helps. Also plan for potential weather-related delays in some hubs and allow generous connection times when choosing the lowest-cost itineraries.
